C本句是一个主从复合句，主句含有情态动词can，动作go还未发生，属于将来时；
25、因此，when引导的时间状语从句要用现在时；当go动作发生时，finish动作已经完成了，应选 C。当然，空格出还可以用finish。如：She will go to bed when she has done/ finishes her homework.You can go to play football if you have finished your work.2. C此题考查need的用法，还要理清句子结构。that前是个主句，that引导的是个定语从句，其先行词是a site，定语从句中谓语动词应该用单数needs，many people think是插入语，空格处是谓语局部。
26、插入语经常被出题人放在题目中，使句子复杂化，增加句子的难度，做题时可以把插入语去掉，便于理解句子结构。need既可用作情态动词也可用作行为动词，主要用法如下：作情态动词时表示“需要；必须，后面当然跟动词原形，仅用于否认句或疑问句中，否认式是neednt，在肯定句中一般用must, have to, ought to或should代替，如：You neednt buy the book.Need I finish the work today? Yes, you must. 作行为动词时，有时态、人称和数的变化，后面跟to do，否认形式要用dont/doesnt/didnt need，如：He
27、 needs to finish it this evening. need用作行为动词时，后面还可以跟动名词或名词，此时含义跟need后面用不定式的含义不一样。“need +动名词含有被动意义，类似这样的用法还有有want, require，如：Our classroom needs cleaning. = Our classroom needs to be cleaned. 既可用作情态动词也可用作行为动词的还有dare。3. B考查情态动词时态。 题干意思是“我没料到你今天会来。你该事先打 来，表示“本没料到用过去时，后面用情态动词+完成时表示对过去的虚拟，本来可以做某事而实际上没有做。
28、情态动词+进行时表示目前正在进行的动作或状态。4. C此题中的could也表示请求而非表示过去时，语气委婉，主要用于疑问句，不可用于肯定句，答语应该用can即could不能用于现在时态的简略答语中，如：Could I come to see you tomorrow morning?Yes, you can. 否认答语用No, Im afraid not.5. A前半句是虚拟语气，“要不是我站在梯子下面接住你，你现在不会站在这里笑了，表示的是现在的情况，用进行时。6. A情态动词must可以表示“偏偏的意思，是一种无可奈何的语气，句子意思是“你为何偏要打断我呢？7. D8. B根据一般逻辑，答
29、语应该是“不，我不会的，wont表示主观的意愿、意志。9. B从后文的将来时可以断定考试的结果还不确定，只是在进行推测，故排除A、C，D的语气不对，只有might表示语气不确定的“可能，符合题意。10. C容许某人的要求，要用I will 来表示“一定或“我决心做某事。11. Cjust now是表示过去的时间状语。情态动词在表示过去发生的事时，必须用“情态动词+have+过去分词的形式。所以只能在选项B或C中确定 答案。Mustnt have eaten是一个错误选项，因为mustnt+动词表示“禁止，不表示判断或推测。这句话的意思是：. 噢，我觉得胃不舒服。我刚刚不应该吃那么多炸鸡。12.
30、 B由题干而知不用被动，排除选项D；题干说“已经丢了，排除选项C；选项A“情态动词+动词原形，表示对现在或将来的事情推测；选项B“情态动词+动词的完成时表示的是对过去或已经发生的事情的推测判断，所以选B。17. B此题考查情态动词。mustnt这里表示“不允许，禁止，此句中相当于cant . shant . 句意：汤姆，你不可以表禁止把衣服这样丢在地板上。13. Cmay也许，口气不肯定，另外后句的she isnt quite sure yet.已给出暗示。shall用在陈述句中与第二. 三人称连用表示允诺，命令等。must:必须can:能够，也可表“推测但常用于否认句。14. D情态动词十h
31、ave done，可表示过去没有实现的可能性，意为本来可以(可能)。 我本来应该请他吗？是由should+have done构成的虚拟条件。15. C情态动词十have done，可表示猜想,这种句子结构的反意疑问句应该与情态动词无关，而与后面的完成结构一致，如果有过去的时间状语，那么用一般过去时反意疑问。如：You must have lived there last year, didnt you?16. C如选A ,只表示与现在事实相反，而主句中would have run 表示与过去事实相反，应该用If I had had time,表示。如果从句中含有系动词、情态动词或助词时，可省略
32、if把从句中的were，had或should提到其主语前形成倒装结构。17. D当insist作坚持说讲，即坚持事实是怎样时，后边that从句不用虚拟语气insist作坚持要求讲，that引导的宾语从句中用虚拟语气。18. Bused to和would都有“过去常常之意，但used to有今昔比照之意，现在再也不这样了。而would无此用法。19. D因对话是对过去事情的推测，所以不能选择A和B。从上句意义可知：已坐了5个人的小车里再挤一个人一定不是舒服的旅行。答案为D。20. C “我们本不该觉得这么累，我们只是参加了个聚会嘛。have been to是已发生的事实，“本不该也是已经存在的状
33、况。shouldnt have felt是对已存在的情况的虚拟。shouldnt“(照常理)本不应该。21. C对过去发生的事情的否认推测。句意：有人告诉我John今天上午又出车祸了。我不相信。他不可能那么粗心的。couldnt have done意为“不可能做了。22. DA、B项因为第二空有并列连词，排除，C项第一空意思不对，排除；D项第一空表示“将来的时间，第二空表示“转折的含义。通顺。23. C根据语境，是对过去了的事情表示感谢。情态动词 + have done，表示过去。would意为“会，将。24. C首先排除B、D，B表示一种委婉，此时没必要，D项must语气不对。shall表单
34、纯的将来，而will更好，表示我们将来愿意去。25. Dcant have done表示对过去的行为动作的否认，从上文来看“根据我所了解的情况，他们不可能这个假期很快乐，A项表示“可能已经，该已，B项表示“过去该做而未做，C项表示“本来不需做而实际上做了。26. Cshouldnt have come意为“本不应该来 ，暗含 “她来过了 的意思，与题意不符；neednt have to come中need为情态动词，倾向于主观上的“必要，与题中给出条件“We had changed our plan不符；didnt need to come中的need to do表示“(有责任、有义务)做某事
35、，符合题意。27. Dcancould not +have done用于疑问句或否认句时，表示对过去情况的推测.表示不可能作过某事。28. A考查情态动词表达推测。can通常用于否认或疑问句中表示推测，表示可能性。这句话的意思是“布什先生一直按时做好所有的事，他怎么可能开幕式迟到呢？。用于否认句表示“不可能，此时要与may not“可能不的含义注意区分，如：She may not tell lies. 她可能没撒谎。He cant have been to your home. He doesnt know your address. 他不可能去过你家，他都不知道你们家的地址。can用在肯定句
36、中也有表示推测的意义，但表示理论上存在的可能性，翻译成“有时可能但很少发生，如：Even experienced teachers can make mistakes.29. C第一空可以用should或must，表示根据规定“应该；必须，第二格只能用will，表示对目前或将来情况的推测。30. C根据句意“幸亏飞行员保持镇静，要不然这场事故是不会防止的，对过去的推测。31. Dought to除了可以跟should一样表示“应该之外，还可以表示推测，“照理应该，而must表示相当肯定的语气，“一定；必定，此题还着重考查正确使用时态，表示到目前应该已经发生用ought to +完成时态。32.
37、 C表示“你可以用you may或you can都正确，B项肯定不对，关键还是need的用法，根据下文He will surely phone you soon，可知“你没必要，因此排除A，mustnt“不许；禁止，语气不对，D错在主谓搭配不一致。33. D先确定问句为将来时态，因为像come, go, leave, start等等这类趋向动词的进行时表示将来时。这是至关重要的，因为答语是就一将来的动作作出判断的。先排除A项，must not译为“不准，与 文意不合；再排除B项，至少cannot不可分开写；最后排除C项， need not译为“不必，与文意相左；只有选D项，译为“可能不，不一定
38、，正好与后文的He likes driving his car相吻合，故应选D项。34. Cshould按道理应该；句意：既然你在驾校时做了大量练习，那么通过这次考试理不应该有困难。35. DThey would have bought that house给我们的信息在那时。 D项为陈述语气，陈述当时没有钱这一事实。C应该表达成与过去事实相反的虚拟句If they had had enough money.36. Bwish后that引导的宾语从句中用虚拟语气。表示与过去事实相反用Hadnt left。37. Bshould意为“竟然。should have done意为“竟然做了某事。句意
39、：我很惊讶，他竟然比赛输了。38. Cshould have done意为“本该干某事。must have done 意为“准是做了，不合题意。39. Dought to可以表示“根据外界的事实或条件做出判断。can用于推测时常出现在否认句或疑问句中；may和might表示推测的不确定性。40. D从by now看应该是完成时态，排除B、C，从It usually takes four days看，应是ought to“应该，选D。41. A选项A表示“在某种意义上应该干；选项B、D均表示“过去的一种可能性。根据题意，只能选A。42. B句意：对大多数植物来说，当受到威胁时竟不能站起来并逃走，
40、因此，经常会被动物吃掉是他们面临的最严重问题。显然，B项正确。43. Acan用于疑问句表示推测。44. A考查should与动词不定式的完成时连用的含义。should have done表示本来应该做而实际上没做，shouldnt have done表示本来不该做但实际上做了。此题的问句意思是“我单项选择题为什么做得那么慢？，答复“我想你没有意识到你本该好好利用上下文。45. C此题考查语境中判断情态动词语气的能力。此题中应该用mustnt“不准；不允许，因为“病人太虚弱了，May I 提问时一般可以用Yes, you may./ No, you cant.语气重一点用mustnt。注意mu
41、stnt不表示“不必，neednt才是“不必。46. D此题考查情态动词的用法。从句意可知那个驾驶员在听了交警对他的控告后作出辩白“这是不可能的，我的车时速超不了80公里，表示对过去的事做出否认推测用couldnt have done。47. C从下文he had gone to a trip，可以断定你不可能见到他，用cant，判断时态是指过去，用cant have (seen)。48. B此题中dare是行为动词，因为without后面跟行为动词的动名词形式，情态动词没有动名词形式。49. C此题还是考查need作为行为动词和情态动词的用法。“需要修改用行为动词need可以说成needs
42、correcting = needs to be corrected，用情态动词need可以说成need be corrected，参考以上表达方式来进行第二空的选择，可见只有C项的两局部都正确。50. C考查情态动词中时态的使用。根据上文可知是在描述现在的动作，因此用情态动词+进行时，同时考查情态动词的含义，表示有把握的推测用must。51. D根据otherwise可以判断出要用虚拟语气。表示过去发生的事要用would have scored.句意：在踢球前他犹豫了一会儿，否那么他就会射中球门。52. Cmust这里表示“偏要。句意：我告诉我女儿该做什么，不用说，她偏要做相反的事。53. A意为：那再好不过了。用could表示客气，用“否认词+比拟级表示最高级。B. C不客气，不礼貌，不符合西方习惯。D为：由你来决定。前顺在征求你的意见，答语怎能还由人家来定呢？54. BShall和第三人称连用，疑问句形式用来征求听话人的意见。
